The Real Housewives of New York City's explosive season seven reunion is coming to a close, but not without a little trip down memory lane to the infamous Turks and Caicos trip the gave birth to Countess Luann de Lesseps' single "Girl Code (Don't Be So Uncool)."

In the exclusive clip below, Ramona Singer goes into the secret history of the naked stranger who startled Heather Thomson so much she ran around the house in tears trying to find out which RHONY lady brought him to the vacation home and left him alone to his own (naked) devices.

Here's what happened: They all decided to go to this karaoka karaoke bar and Luann met "this nice looking guy" and he had a "very good friend." If you believe Ramona, she said it was Luann's decision to bring the guys home. "Oh it was all my idea, right?" Luann laughed. And what about Sonja Morgan? She was there, to Luann's surprise, but there was no man for her. As for what Ramona recalls about the night, well there was loud music. "We're dancing, we're drinking, we're having fun," she said. "I was so tired, it must be 3 or 4 in the morning. I don't know what time it is and the guy said to me, ‘I'm tired. I need to get home, but I don't know how to get home. Can I crash here?' I said, ‘Well, I guess so!'"

She forgot about the empty bedroom downstairs and sent him to Bethenny Frankel's empty room (adjoined to the room occupied by Heather and Carole Radziwill) and instructed him never to go into the bathroom that they shared. "You cannot use this bathroom, ever," she said she told him, along with, "Listen, you better be out before anybody wakes up."

Did he listen? Partially because he was spotted by Heather. And then he made his way downstairs to have some juice. The rest is Housewives history. We have a song for the summer and fractured friendships because of it.

The Real Housewives of New York City Reunion: Part 3 airs Thursday, Aug. 27 at 9 p.m. on Bravo.
